Significant volume decrease when using Comcast cable box

The volume control on the cable box would be defective whlist calling your cable company will help specially if its comcast. Try connecting the cable direct to the back of the tv bypassing the cable box. Update me with your findings.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

yes direct into the buttons the WD40 is the best thing i've ever seen, that will not damage anything you can spray it without fear and then try to activate the buttons a few times, of course with the tv off.

This low audio problem happened to me suddenly yesterday. I powered off over night - no change. I plugged the A/V cables into a second TV - no change. I called Comcast - problem solved.
Tap these buttons on the remote;

please could you send me tips of what the problem of my plasma keeping stuck pixiel panorama LCD Tv model 42LC68T

Akai does not publish the remote codes. I had a tough time trying to get my akai LCT42 to work with another remote. I bought an universal remote URC R6 at walmart for $19. I can now operate the tv, u-verse cable box, panasonic surround all from this remote including menu's channel, volume, record with the dvr & more. I hope this helps..........

Good luck.

Connect the HDMI outputs on your various components to the HDMI inputs on your receiver. Connect the HDMI output on the receiver to the input on your TV. HDMI incorporates digital audio, so no need to buy optical audio cables. If your receiver does not have HDMI inputs for all your components, you will need to make a choice. HDMI = Best, component video + optical audio = second best, S-video+ optical audio = third best

maybe defective speaker or audio output ic or shorted capacitor within audio circuit

Sounds like a power supply issue. Does the power indicator light up? Can you hear a click when the power button is pressed?

The answer depends whether its a Comcast DVR Remote or a regular one. The DVR codes are 4 digit -- the others are 5 digit. I got 0060 to work for my DVR remote.

I have an Akai 42"lct & had the same problem. I bought an universal remote URC R6 at walmart for $19. I can now control the tv, u-vrerse cable, panasonic surround system & still have the aux open. You must use the "learn" method but I can control channels, volume, record, menues for all devices as well as setup, record for dvr & more. I hope this helps.........
